ME'CHANISM Fon PRoDUoINe ARTIFICIAL SILK of the boroufgh of Manhattan, city, county,vv

and State of New York, have invented certain new and useful Improvementsin Mech- 1 anism for Producing ArtiicialSilk.

My invention relates to that lportion of. apparatus employed in the manufacture ofartificial silk in which the viscous liquid is transformed into fine raw fibers and hasfor its object to create mechanism whereby,y the raw thread produced is caused to comprise a number of twisted filaments of great fineness.

In the drawings Figure 1 is aside view partly in section showing two adjacent filament producing devices and their 4connections with the source of supply ofviscous fluid. Fig. 2 is a sectional view through the line 2 2 of Fig. \1;'Fig. 3 'is a sectional view of a. pulley carrying member; and Fig. 4 is a top view thereof. y

In the drawings, a is a source of supply through which the viscousjliquid -is fed into the indivi ual thread forming devices.. The pipe a is preferably made of glass. From the pipe a the fiuid descends into the stem b of the filament forming bulbs c `and nipples d. These three parts, I), c, are preferably made ofglass and of a single piece. -The connectioh betweenthe stem .5 and the pipe a is shown as a cork e at' theright of Fig. 1, and as a perforated piece of lfelt f, on the left hand of Fig. 1 and in Fig. 2. Small tubes or funnels of glass g having extremely .ine orificesx are connected -to the' nipples d by means of the corks h orl othensuitable tween the stem and the driving sleeve. 55. for any cause, it .1s desired to remove the means such as rubber tubes or the like.

Mounted -upon the stationary Aframe z' are the fixed brackets y'. These brackets y' carry rotatively the pulley carrying member or driving sleeve la. The pulleys Z on .'these members are controlled and rotated by belts from a common shaft so that a large nfumber of these spindles can be similarly rotated simultaneously. The stem b fits the interior orifice ofthis 4member c and ,rwhen in operation, the oppositely disposed lugs m preferably` forming part of the stem b rest'within the recesses n of the member 'lewhereby a detachable driving connection is formed lil;-

be done without disturbing the operation Aof the remaining portions of the entire mechamsm by pushing the stem b upwardly vuntil the lugs m become disengaged from the recesses n, then turning the stem b 90 whereupon the lugs m will comeinto register with the oppositely disposed grooves o'v located on the interior surface of the member 7c.` iThe stem b and its connections can then be entirely withdrawn from lthe apparatus. lThe aperture where the stem 'Zr and the pipe a connect is plugged up and` the entire factory is undisturbed while repairsor changes can be made in any one spindle. The connection f comprises a fine piece of felt tapedor otherwise fastened lto the pipe a by means ofl the tapes p and has a special advantage of permitting a rotation of the s teml b in,the

felt packing and avoidingentirely all strain on the glass composing either the pipe a or the stem b. The cork connection e creates such astrain and is Lless desirable for this reason than the felt connection. The operating belts are indicated as g. r-

From the above description it will be seen that myv device is simply disassociatable in all its lparts nand is, capable of producing point. lAs the spindles are rotated by the operation lof the belts g the viscous liquid passes through the fine orifices of thefunnels or tubes g from which veryslender filaments are squirted, so to speak, and simultaneously twisted into a strand at fairly be operated at the same time so that any desired quantity of thread can be produced at any onetime. The twisted threads in the raw condition in which they emerge from .artificial silk without permitting the viscous I liquid coming into contact with air at any -slow speed. Any number of spindles can the device above described are removed from time to time and passed through .the finishin 'chemical and physical processes. v,

aving thus described the nature of my invention what I claim is:

.1. In a device for making artificial silk, the combination of a source of supply, a rotating `part terminating in a multiplicity of apertures, a corresponding number` of neorificed tubes located adjacent to said apertures and joined thereto by a iexible connection.

l2. In a device for makingartificial silk,

the combination of a vitreous bulb provided with an integral stem, and with a plurality ioo of integral depending nipples, a tube 'def part of and having a detachable driving contachably connected with each of said nipples, nection With said stem and a bracket rotatasaid tubes having Ininute discharge orifices, bly supportin said driving sleeve. a source of supply,4 the upper end of said ARRY C.
